Cube is is the 4th master of the Tendo Branch of gaming, mentor to Wikun and the first Tendo practitioner to break the tradition of cartridge based media to use discs. Cube knew that the era of cartridges was coming to an end, and though it put him at a disadvantage to learn the new format on his own, he did so in order to ensure the continued advancement of Tendo Branch. Knowing he would never be able to do more than hold his own against his rival, Perry Staysin, Cube instead turned his focus on raising and training Wikun, who would reclaim the standing of the Tendo Branch.

Cube can be easily recognized by his signature vivid purple suit. He has devoted his studies to learning the new media form that the previous masters had dismissed. Despite his roguish appearance, he is actually quite shy around women. His repeated attempts to get to know the Mote Sisters invariably end in failure due to his inability to communicate with them. Still a nice guy, he often ends up babysitting Ada Vance and her younger sister, Espy, keeping them on child leashes so he doesn't lose track of them. Cube is a bit of a wanderer, and in his travels, has picked up two odd pet birds, Watori and Vetori (Wavebirds)
